Well-groomed doctor seeing nothing (7)
I believe the answer is:
soignee
'well-groomed' is the definition.
('soignee' can be a synonym of 'well-groomed')
'doctor seeing nothing' is the wordplay.
'doctor' indicates an anagram.
'nothing' becomes 'o' (looks like zero - 0).
'seeing'+'o'='seeingo'
'seeingo' anagrammed gives 'SOIGNEE'.
(Other definitions for soignee that I've seen before include "Elegant female" , "No siege laid to well-groomed, classy kind of woman" , "smart" , "Of a Frenchwoman, wellgroomed and sophisticated" .)
